The purpose of the mediation is to resolve disputes in the early stages of the collection process and within 40 days after the mediation application is accepted by the IRS.  In order to be accepted into the process, taxpayers must make a good faith effort to resolve matters with the IRS collection officer followed by a conference with the officer's manager.  Acceptance into the mediation process does not mean that taxpayers can't pursue other options if mediation doesn't resolve their case.
